A $10 million lawsuit charging that the company lied about the product’s all natural ingredients filed earlier this year has been amended citing the label’s description of its tequila content as misleading, reports The New York Post.

Apparently, the SkinnyGirl Margarita label had advertised that it’s made with "100 percent blue agave tequila," but the lawsuit filed by Christopher Rapcinsky and Erin Baker contends that it most likely uses "a lower quality and purity tequila by-product called mixto - essentially a mash of tequila and some unknown additives (rarely organic) which may comprise as much as 49 percent of the final mixed liquor."

The suit alleges that after Frankel sold the company to Beam Global, it removed the “100 percent” claim and replaced it with the statement, "with premium Blue Agave tequila." That change makes it so that any amount of the alcohol would meet the company’s claim, yet the suit says it’s still “extremely misleading.”

Beam Global dismisses the case as “frivolous,” and submitted a statement to the newspaper saying, "Skinnygirl Margarita is made with premium blue agave tequila and meets the highest quality standards. We will defend our case vigorously, and we are fully confident we will prevail."

Frankel isn’t named as a defendant in the suit, because she’s no longer the pre-made mix line's owner. But, she defended the brand in September against charges that the cocktail mix contained preservatives despite the company’s claim that it was “all natural” and contained “no preservatives.”

At the time, a Beam Global company rep confirmed, "Skinnygirl Margarita contains very low levels of sodium benzoate (a preservative) so it can stay on the shelves."

Frankel later said in a statement on her website that “The Skinnygirl Margarita is made with natural ingredients and its label is consistent with U.S. federal regulations.”

THR has requested comment on the new charges, but Frankel’s reps did not immediately respond.
